Therefore, the existence of bijective correspondence between graph embedding and graph rotation enables us to replace graph operations with the operations of graph rotation system, which can guarantee the 2-manifold property of the graph embedding. 由于图形旋转系统和图形嵌入之间存在着&对应的关系,因此我们可以把对图形的操作转换为对旋转系统的操作,从而保证了图形体在经过拓扑变换后依然能够保证其二维流形性。
The bijective linear preservers of rank-additivity on Hn are characterized. 刻划了Hn上秩可加线性保持。
Let H be an arbitrary Hopf algebra over a field k with bijective antipode s. 设H是定义在域k上的一个Hopf代数,反极元s为双射。
Our algorithm was used to bijective mapping, and pretreating before the run time translation. 该算法将XML-TO-SQL查询转换分为两个主要阶段:预处理阶段和运行时翻译阶段。预处理阶段通过识别双射映像,计算最小可辩识祖先进行翻译前准备;
The mapping between input and output sets can be proved to be bijective with the set theory. Then, the affine mapping theory is applied to modeling a class of hysteresis, which is stimulated by smooth periodic signals. 利用集合理论证明了变换后,迟滞的输入输出集合是双射的,从而对在光滑周期信号作用下的一类迟滞非线性进行建模。
And how to evolutionally design bijective S-boxes is also studied in this dissertation. Under the given evolutionary strategy, a large number of bijective S-boxes with high nonlinearity and low differential uniform can be obtained. 另外研究了如何利用基因算法来演化设计双射S盒,在给定的演化策略下,可以设计出大量具有高非线性度和低差分均匀性的双射S盒。
Furthermore, this dissertation proposes a foreign trade volume forecasting model based on bijective soft set, which considers soft information that influence foreign trade volume and uses the reductions of bijective soft set decision system to induce forecasting rules, and proposes an example. 考虑外贸出口量预测的定性信息因素,利用双射软集合决策系统的约减,提取预测规则,提出了基于双射软集合的外贸出口预测方法,并进行了算例分析。
In the scheme, the third party not only holds several normal verification shares which are bijective with each share, but also keeps a special verification share connected with all shares. 在该方案中,可信第三方除了保存与各共享份一一对应的普通验证份外,还持有一个与全体共享份都相关联的特殊验证份。
